application filed February 6, 13-322. Serial lt'o. 53 L440.

T all it may concern:

Be it known that we, Joan E. Korma and RAYMOND PAUL, citizens of the United States, residing at Chicago, in the county of.

like with a sign, legend or advertisement, a

light for illuminating the same, and a plurality of selective circuits controlling the light in a variety of ways to enhance the novelty and etliciency and attractiveness of the device.

Further objects or the invention will become apparent as the description is read in connection with the accompanying drawing showing a selected embodiment of the invention, and in which-s Fig. 1 is a front elevation of a door equipped according to the, invention Fig. 2 is an enlarged view partly in section illustrating a small sign made according to the invention;

Fig. 3 is a, transverse section illustrating a means for making the advertising panels burglar-proof;

Fig. i is a sectional detail of a switch operated by the latch;

Fig. 5 is a similar sectional view of a switch operated by the movement of the door; and

Fig. 6 is a detailed sectional view on the line 66 of Fig. 5.

Referring to the drawing, 10 indicates a door of any suitable form here shown as mounted on hinges 11, 12 and 13, which support it in a suitable door frame. 14:, Figs. 1 and it, indicates a conventional lock including a latch bolt 15 adapted to co-operate with the face plate 16 on the door frame to secure the door in closed position.

17 indicates a small advertising device that may be used to indicate in which direction the door is to be swung as well as to convey certain information to persons pas ingby. As shown in the enlarged view of Fig. 2, the advertising device includes the word Pull in large letters and below it the word Dentist. The wording of the advertisement or other means or communicating the informat on desired is arranged so as to be illuminated by an electric'lamp 18 carried by socket 19 suitably supported within the advertising device. By preference, the socket and bulb are connected by a bayonet joint and a spring, asis customary in lamps used on vehicles, so as to take care of the jars in service. As shown, the front of the advertising device includes a piece of plate glass 20 secured to the door by the frame 21. 4

The door may be equipped with any desired number of advertising devices, and we have here illustrated three to show how they may be disposed about the area covered by the door. In the illustration, the advertis- 111g devices are located in spaces between the lights or panels of the ordinary door construction, but they may be made to replace the panels or in fact, to cover the entire area of the door. When the advertising devices are of any considerable size, it is preferable to equip them with means toprevent thieves or the like from breaking through the glass of the advertising device andgaining entrance'to the building. The advertising device shown at 17 in Fig. 1 is too small to involve any danger or this sort, but the de vices at 22 and 23 are of sufficient size to require some protection. As illustrated in Fig. 3, we prefer to makean opening entirely through the door and fit therein a pair of strong plates 24 and 25 having suit-' able flanges 26 equipped with passages for large'screws 27 by which they are secured to the door. These plates are fastened together by the transverse screws 28 which should have their heads toward the inside of the building so as to prevent removal after breaking away the glass and other parts of the advertising device. The plates are preferably tapered, as shown, towards the middle and are there provided with an opening for a lamp. Adjacent to this opening the plates have scmi-c rcular bosses 29 between which a lamp socket is secured by a screw 30. Each plate 24 is equipped with a reflector 31 which may be of any suitable shape and secured in place by any desired means; As here shown, the reflectors are secured to the flanges 26 by screws 32. Outside of each reflector and resting against the door adjacent to the edges of the opening is a plate of glass 33 upon which is laid a I sheet of celluloid 34 against which the plate glass closures 35 are clamped by frames 36.

- bottom and top of the openings in the door have their edges beveled as indicated at 37 and the frames 36 are provided with openings 38 communicating with the interior of the advertising devices.

The construction just described is intended for use when advertising matter is to be placed on both sides of the door. When only one side is to display an advertisement, the plate 24 may be omtted and the corresponding reflector and glass pieces may be replaced by any suitable closure. The burglar-proof plate 25 is suiiicient to protect the opening, and the screws 27 and 28 having their heads towards the inside of the plate, cannot be removed from the outside.

We prefer to use electric lightsin these advertising devices and to use a transformer to makethe available current suitable for the small lamps required. As a general thing, 6 or 8 volts will be sufficient to operate the lamps'required; I

Undercertain conditions it is desirable to have these advertising devices illuminated as the door is opened and closed so as to attract the attention of persons passing therethrough, and give them certain information. In other cases it is desirable to have the illumination when the door is closed, in others 44 which has a blade or leaf 45 pivoted so as to make selectivecontact with the buttons 46, 47, 48, 49 and 50. When the leaf is in contact with the button 50 the circuit is closed through a switch 51 operated by-the' latch bolt 15 and a switch 52 0 erated by the movement of the door. hen the leaf is in contact with the button 49 the circuit is closed through the switch 52 alone. When the leaf is in contact with the button 48 the, circuit is closed through the hinges 11 and 13 and the switch 53. When the leaf is in contact with the button 47 the circuit is closed through the hinge 12 and the illumination is continuous. And when the leaf is in contact with the button '46 as shown in Fig; 1, the lights are all oil.

The switch 51 Figs. 1 and 4 comprises an angular leaf spring 54 secured to the door frame by a screw 55 connected to a wire 56.

The free end of the switch is equipped with an insulating block 57 adapted to contact with the latch 15, and a contact piece 58 for co-operation with the face plate 16, the contact piece 58 being connected to the button 50 by a wire 56 When the door is closed the spring 59 of the latch 15 normallyholds the switch 51 open but when the knob is turned to withdraw the latch, this switch closes the circuit and if the leaf 45 of the multiple switch 44 is resting on the button 50, the light or lights in the circuit will be lit.

The switch 52 Figs. '5 and 6 is here illustrated as including a pivot member 60 carried by the-door, and a fixed member 61 carried by the door frame. 60 is pivoted by a pin 62 to the face plate 63 and a spring 64 normally tends to hold it inposition to project from the edge of the door. Back of the face plate 63 is a The member socket 65 into which the member 60 swings leading to the lamps in the advertising devlces.

It will be clear: from this construction that when the door 10 is closed, the switch 52 will be closed, and if the switch 51 is closed by withdrawing the latch 15, the light or lights in the advertising devices will. be lit until the door is swung sufiiciently to open the switch 52 and will be again lit when the door returns to the position in which the switch 52 is closed. This flash of light in the advertising device or devices as the door is opened and closed will serve to attract attention of persons passing and is most suited to give directions for pushing or pulling the door and directions for turning after paming through the door together with an indication as to the occupant of the room or building.

In order to have the advertising devices illuminated while the door is closed, and

. dark when the door is open, the switch leaf provide the switch 53'which may be of any suitable form that will close when the door is opened and open when the door is closed. This switch is connected by the wire 74 with nearer? the hinge 13 which in turn is connected by the wire 7 5 with the buttom 48 of the switch 44. The opposite side of switch 53 is connected by the wire 76 with the lamp or lamps in the door, from which the circuit proceeds through'wire 77 to hinge 11 and from hinge 11 by wire 78 back to the line 42.

An additional circuit is also provided in order to make it possible to continuously illuminate the signs or other devices on the door. Thisis accomplished by providing a third hinge 12 and connecting it with the button l7 by the wire 79 and with the wire 76 by the wire 80. By this means a circuit is formed from the button 47 through the hinge 12 to the lamps and from the lamps back to the line 42 through the Wires'77 and 78 and the hinge 11.

From the foregoing it will be clear that a door, gate or the like may be equipped with one or moreilluminated signs bearing advertising matter, directions. or the like and that the lamp or lamps providing illumination may be controlled by shifting a switch, blade or leaf so as to have illumination continuously or only when the door is open, or only when the door isshut, or only when the door is shut and unlatched' as may be desired. The wiring here illustrated is very satisfactory in service, but those skilled in the art may make suitable variations to take care of conditions different from those specified. However, the examples here given will suthce to disclose the invention so that it may be made use of in varying conditions to be met in practice. We have shown the invention as applied to a hinged door of conventional type but it will be obvious that the principles are applicable to revolving doors, sliding doors and the like.
